Pole Barn Builders in Spokane County and North Idaho
Spokane Pole Building Co. routes projects across two states, each with its own permitting and licensing rules. Here's how coverage and requirements break down by county.
Spokane County coverage
Spokane County projects generally follow the City of Spokane's BP-14 pathway where the building qualifies as non-engineered: up to 3,000 square feet including lean-tos, 36 feet of maximum width, and a design snow load capped at 39 pounds per square foot ground, 30 pounds per square foot roof. Coverage spans Spokane, Spokane Valley, Cheney, Airway Heights, Deer Park, Medical Lake, Mead, and Colbert, with acreage properties outside city limits following county rather than city permitting.
North Idaho coverage
North Idaho coverage centers on Kootenai County: Coeur d'Alene, Post Falls, Hayden, Rathdrum, Athol, and Dalton Gardens. Permitting looks different than Spokane County. Unincorporated Kootenai County exempts detached accessory structures of 200 square feet or less from a building permit, with a 10-foot eave height cap and roof projections limited to 24 inches, and separately exempts true agricultural buildings from the state building code under Idaho Code Section 39-4116, though a location permit is still generally required. Neither exemption applies once a project sits inside city limits like Coeur d'Alene or Post Falls, where local city code controls instead.
Licensing across two states
Washington requires construction contractors, including post-frame builders, to register with the Department of Labor & Industries under RCW 18.27, with bond minimums of $30,000 general or $15,000 specialty, and liability minimums of $200,000 or $250,000 combined depending on contractor type. Idaho requires contractor registration, not licensure, through the Division of Occupational and Professional Licenses for any job over $2,000 in combined labor and materials, unless a specific exemption under Idaho Code Section 54-5205 applies. The two systems aren't interchangeable, and property owners should confirm a builder's registration directly in whichever state the project sits in.
Permits differ by county
"What permit do I need" doesn't have one answer across this coverage area, because Spokane County and Kootenai County run genuinely different processes. Spokane's BP-14 guide sheet is a published, defined pathway for qualifying non-engineered pole buildings, with clear caps on size, width, and snow load, plus a minimum 6-inch by 6-inch pressure-treated column set at least 3 feet 6 inches deep in a 4-foot hole. Projects that exceed those caps move to a full engineered design and standard building permit process instead.
Kootenai County's exemptions are narrower and easy to misread. The 200 square foot detached-structure exemption covers small accessory buildings like sheds, not a shop or barn of any real size, and only applies in the unincorporated county, not inside a city. The separate agricultural building exemption under Idaho Code Section 39-4116 applies to genuine farm-use buildings, with a location permit still typically required even when the structure itself is exempt from the state building code. Getting the right answer means confirming the exact rule for your parcel and building use, in the county it actually sits in, rather than applying a rule from across the state line.

Service area questions
Do you serve Kootenai County, Idaho?
Yes. Spokane Pole Building Co. routes projects throughout Kootenai County, including Coeur d'Alene, Post Falls, and Hayden, alongside coverage across Spokane County, Washington. The two counties sit close enough together that many builders in the network work across the state line, though permitting and licensing rules don't carry over between them.
Is there a size that skips a permit in Kootenai County?
Only a narrow one. Unincorporated Kootenai County exempts detached accessory structures of 200 square feet or less, such as a shed or playhouse, from a building permit, with a 10-foot eave height cap and roof projections limited to 24 inches. That exemption doesn't apply inside city limits, and it doesn't cover a full-size shop or barn.
Is snow load different in North Idaho than Spokane?
Yes, and it's not a single number on either side of the state line. Spokane and Spokane County use a 39 pound per square foot ground snow load baseline for design. North Idaho snow load requirements vary by specific jurisdiction and elevation rather than one countywide figure, so confirm the number for your exact parcel before finalizing a design.
Is contractor licensing the same in Washington and Idaho?
No. Washington requires L&I contractor registration under RCW 18.27, with set bond and liability minimums, for any construction contractor including post-frame builders. Idaho requires contractor registration, not licensure, for jobs over $2,000 in labor and materials, unless a specific exemption applies. A builder registered in one state isn't automatically compliant in the other.
